British politics is in chaos on Thursday after a scandal over Israel and anti-Semitism devolved into a vicious fight over the views of Nazi leader Adolf Hitler.

The scandal had already seen Naz Shah, one of Britain’s few female Muslim members of Parliament, suspended from the Labour Party on Wednesday. On Thursday, Ken Livingstone, the controversial former mayor of London, was also suspended from the party and publicly accused of being a “disgusting” Nazi apologist by a Labour colleague.

For many in Britain, the scandal is part of a wider problem for Labour’s left wing, which has come to dominate the party after the selection of Jeremy Corbyn as leader last year. This wing of the party has generally supported Palestinian causes — but some rivals say that support has been tainted by anti-Semitism within the party’s ranks.
